# X_UPGRADE_DIRTY_TREE

## Means

x upgrade refused a tree with uncommitted changes

## Typical cause

git status reports changes, or the directory is not a git repository: a hop must be one reviewable commit, and git is the only state between runs

## Fix

`git status --short` — then commit or stash, and re-run: x upgrade --json
